Refrigerator appliances having multiple freezer chambers

ABSTRACT

A refrigerator appliance is generally provided herein. The refrigerator appliance may include a cabinet extending along a vertical direction from an upper portion to a lower portion. The cabinet may also extend along a transverse direction from a rear portion to a front portion. The cabinet may define a plurality of operably-independent chilled chambers and, optionally, a modular ice making assembly.

FIELD OF THE INVENTION

The present subject matter relates generally to refrigerator appliances, and more particularly to refrigerator appliances having multiple freezer chambers.

BACKGROUND OF THE INVENTION

Certain refrigerator appliances utilize sealed systems for cooling chilled chambers of the refrigerator appliances. A typical sealed system includes an evaporator and a fan, the fan generating a flow of air across the evaporator and cooling the flow of air. The cooled air is then provided through an opening into the chilled chamber to maintain the chilled chamber at a desired temperature. Air from the chilled chamber is circulated back through a return duct to be re-cooled by the sealed system during operation of the refrigerator appliance, maintaining the chilled chamber at the desired temperature.

Certain refrigerators appliances also include one or more fresh food and/or freezer chambers configured for maintaining different temperatures for storing different types of food and drink. For example, a conventional refrigerator appliance may be formed as a side-by-side configuration wherein a fresh food chamber is positioned beside a freezer chamber. Both the fresh food chamber and the freezer chamber will generally extend from the top of the refrigerator appliance to the bottom of the refrigerator appliance. As another example, a conventional refrigerator appliance may be formed as a bottom-mount refrigerator appliance wherein a freezer chamber is positioned below a fresh food chamber.

However, problems exist with conventional refrigerator appliances. In the case of side-by-side refrigerator appliances, usable space is generally limited by the width of the chambers. In other words, a user may be unable to place certain objects within the fresh food chamber since its width of is necessarily limited by the width of the freezer chamber. In the case of a bottom mount refrigerator appliance, it may be difficult to organize and/or access certain items. Small items, as an example, may fall to the bottom of the freezer chamber, where they may become lost or inaccessible. What's more, any components for making ice may significantly and permanently limit the volume within the refrigerator appliance that would otherwise be available for storage.

In turn, further improvements for refrigerator appliances would be beneficial. For instance, it would be beneficial to have a refrigerator appliance addressing one or more of the above issues. Moreover, it may be beneficial to have a refrigerator appliance with one or more features for varying the amount or size of chilled storage space within a cabinet.

As used herein, the terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components.

Turning now to the figures, FIGS. 1 and 2 provide multiple views of a refrigerator appliance 100 according to exemplary embodiments of the present disclosure. FIG. 1 provides a perspective view of refrigerator appliance 100. FIG. 2 provides a front view of refrigerator appliance 100 with multiple doors 128, 130, and 132 shown in an open position.

Refrigerator appliance 100 generally includes a cabinet or cabinet 102 that extends between an upper portion 104 and a lower portion 106 along a vertical direction V, between a first side portion 108 and a second side portion 110 along a lateral direction L, and between a front portion 112 and a rear portion 114 along a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another.

Cabinet 102 defines a plurality of chilled chambers for receipt of food items for storage. In some embodiments, cabinet 102 defines a fresh food chamber 122 and one or more freezer chambers 124, 126. For instance, in some embodiments, fresh food chamber 122 is defined between discrete top and bottom freezer chambers 124, 126. In turn, a top freezer chamber 124 may be positioned at the upper portion 104 of cabinet 102 while a bottom freezer chamber 126 is positioned at the lower portion 106 of cabinet 102. Each chilled chamber 122, 124, 126 is generally accessible (e.g., to add or remove items within refrigerator appliance 100 along the transverse direction T) through a separate opening 134, 136, 138 at the front portion 112 of cabinet 102. Specifically, a top freezer opening 134 is in communication with (and permits access to) top freezer chamber 124; a middle fresh food opening 128 is in communication with (and permits access to) fresh food chamber 122; and a bottom freezer opening 136 is in communication with (and permits access to) bottom freezer chamber 126. It is understood that each chamber 122, 124, 126 is generally separated by one or more horizontal mullions formed from an insulating material such as foam. In addition, to provide structural support, a rigid injection molded liner or a metal frame may surround the insulating foam and further separate the chambers 122, 124, 126. In turn, each chamber 122, 124, 126 may be maintained at a unique temperature (e.g., between around 0° F. and 57° F.).

Advantageously, fresh food chamber 122 is provided at a comfortable and readily accessible height (e.g., such that most users will be able to view the entire height of fresh food chamber 122 without bending over). Moreover, at least a portion of the total freezer space (i.e., combined total volume of freezer chambers 124, 126) is provided at an elevated height that may be easily viewed and accessed (e.g., without bending over).

In certain embodiments, the total freezer space may be further segmented or divided into discrete compartments. As an example, a first top freezer compartment 162 may be provided separately from a second top freezer compartment 164. One portion of top freezer chamber 124 (e.g., first top freezer compartment 162) may be proximal the first side portion 108 of cabinet 102, while another portion of top freezer chamber 124 (e.g., second top freezer compartment 164) is proximal the second side portion 110 of cabinet 102. An upper mullion 170 may extend between top freezer compartments 162, 164 along the transverse direction T (e.g., from the front portion 112 to the rear portion 114 of cabinet 102). In other words, the top freezer compartments 162, 164 may be separated and spaced apart from each other along the lateral direction L. Upper mullion 170 may generally be formed from an insulating material such as foam. In addition, to provide structural support, a rigid injection molded liner or a metal frame may surround the insulating foam. Additionally or alternatively, upper mullion 170 may be a vacuum insulated panel or may contain a vacuum insulated panel to minimize heat transfer between first top freezer compartment 162 and second top freezer compartment 164.

As another example, a first bottom freezer compartment 166 may be provided separately from a second bottom freezer compartment 168. One bottom freezer chamber 126 (e.g., first bottom freezer compartment 166) may be proximal the first side portion 108 of cabinet 102, while the other bottom freezer chamber 126 (e.g., second bottom freezer compartment 168) is proximal the second side portion 110 of cabinet 102. A lower mullion 172 may extend between bottom freezer compartments 166, 168 along the transverse direction T (e.g., from the front portion 112 to the rear portion 114 of cabinet 102). In other words, the bottom freezer compartments 166, 168 may be separated and spaced apart from each other along the lateral direction L. Lower mullion 172 may generally be formed from an insulating material such as foam. In addition, to provide structural support, a rigid injection molded liner or a metal frame may surround the insulating foam. Additionally or alternatively, lower mullion 172 may be a vacuum insulated panel or may contain a vacuum insulated panel to minimize heat transfer between first bottom freezer compartment 166 and second bottom freezer compartment 168.

In additional or alternative embodiments, such as those shown in FIG. 2, fresh food chamber 122 is advantageously provided as a single continuous chilled chamber within cabinet 102. Fresh food chamber 122 may occupy the full internal width of cabinet 102. In other words, fresh food chamber 122 may extend in the lateral direction L from the first side portion 108 to the second side portion 110.

According to the illustrated embodiments, various storage components are mounted within fresh food chamber 122 and freezer chambers 124, 126 to facilitate storage of food items therein as will be understood by those skilled in the art. In particular, the storage components include bins 146, drawers 148, and shelves 150 that are mounted within fresh food chamber 122 or freezer chambers 124, 126. Bins 146, drawers 148, and shelves 150 are configured for receipt of food items (e.g., beverages and/or solid food items) and may assist with organizing such food items.

Various doors may be mounted to cabinet 102 to selectively open and close a portion of the one or more chilled chambers 122, 124, 126. As an example, a top door 130 may be rotatably mounted to cabinet 102. One or more top doors 130, such as a pair of French doors, may be rotatably mounted at the upper portion 104 of cabinet 102. Top doors 130 may selectively move (e.g., pivot) between an open position (FIG. 2) and a closed position (FIG. 1). As shown the open position of each top door 130 may generally permit access to a corresponding portion of top freezer chamber 124 (e.g., through top freezer opening 134). In some such embodiments, a first top door 130 mounted proximal the first side portion 108 covers first top freezer compartment 162 in a closed position and permits access to first top freezer compartment 162 in an open position. A second top door 130 mounted proximal the second side portion 110 covers second top freezer compartment 164 in a closed position and permits access to second top freezer compartment 164 in an open position.

As another example, one or more bottom doors 132, such as a pair of French doors, may be rotatably mounted at the lower portion 106 of cabinet 102. Bottom doors 132 may selectively move (e.g., pivot) between an open position (FIG. 2) and a closed position (FIG. 1). As shown the open position of each bottom door 132 may generally permit access to a corresponding portion of bottom freezer chamber 126 (e.g., through bottom freezer opening 136). In some such embodiments, a first bottom door 132 mounted proximal the first side portion 108 covers first bottom freezer compartment 166 in a closed position and permits access to first bottom freezer compartment 166 in an open position. A second bottom door 132 mounted proximal the second side portion 110 covers second bottom freezer compartment 168 in a closed position and permits access to second bottom freezer compartment 168 in an open position.

As yet another example, one or more middle doors 128, such as a pair of French doors, may be rotatably mounted between top freezer chamber 124 and bottom freezer chamber 126. Middle doors 128 may selectively move (e.g., pivot) between an open position (FIG. 2) and a closed position (FIG. 1). As shown the open position of each middle door 128 may generally permit access to a corresponding portion of fresh food chamber 122 (e.g., through a portion of middle fresh food opening 128). In some such embodiments, a first middle door 128 mounted proximal the first side portion 108 covers one portion of half of fresh food chamber 122 in a closed position and permits access to fresh food chamber 122 in an open position. A second middle door 128 mounted proximal the second side portion 110 covers another portion or half of fresh food chamber 122 in a closed position and permits access to fresh food chamber 122 in an open position.

In order to prevent or restrict leakage of cool air, doors 128, 130, 132 and/or cabinet 102 may define one or more sealing mechanisms at the interface where the doors 128, 130, 132 meet cabinet 102. In some such embodiments, each door comprises a discrete perimeter gasket 174 (e.g., foam seal or rubber gasket) to sealingly engage the cabinet 102 in a closed position and isolate the corresponding chilled chamber from the other chilled chambers 122, 124, 126.

Refrigerator appliance 100 further includes a controller 144. Operation of the refrigerator appliance 100 is generally regulated by controller 144. Controller 144 may be provided in communication (e.g., electrically coupled) with a panel. In exemplary embodiments, a control panel is included as general purpose I/O (“GPIO”) device or functional block. In other exemplary embodiments, a control panel is included with multiple input components, such as one or more of a variety of electrical, mechanical or electro-mechanical input devices including rotary dials, push buttons, touch pads, and touch screens. The control panel may be in communication (e.g., electrically coupled) with controller 144 via one or more signal lines or shared communication busses. Moreover, controller 144 may be in communication with a sealed refrigeration system (not pictured) directing cooling operations of refrigerator appliance 100. During use, controller 144 may initiate cooling operations (e.g., cooling airflows) within the various chilled chambers 122, 124, 126. Optionally, each chilled chamber 122, 124, 126 may be operably independent such that a discrete operating temperature may be selected for each chilled chamber 122, 124, 126. For instance, refrigerator appliance 100 is able to maintain top freezer chamber 124 at separate temperature from bottom freezer chamber 126. Additionally or alternatively, the separate freezer compartments 162, 164, 166, 168 may be maintained at separate or unique temperatures. As an example, one freezer compartment (e.g., first top freezer compartment 162) may be maintained at a specific relatively low temperature (e.g., around 0° F.), while allowing another freezer compartment (e.g., second top freezer compartment 164) of the same chamber (e.g., top freezer chamber 124) may be selectively adjusted anywhere between the freezer temperature and a fresh food compartment temperature (e.g., between around 0° F. and 37° F.). Additionally or alternatively, the bottom freezer compartments 166, 168 may be maintained at similar unique temperatures.

Controller 144 includes memory and one or more processing devices such as microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of refrigerator appliance 100. The memory can represent random access memory such as DRAM, or read only memory such as ROM or FLASH. The processor executes non-transitive programming instructions stored in the memory. The memory can be a separate component from the processor or can be included onboard within the processor. Alternatively, controller 144 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.

Turning now to FIGS. 2 through 6, some embodiments include one or more modular components that may be selectively used within or separate from the rest of refrigerator appliance 100. For instance, some embodiments include a modular ice making assembly 200. Modular ice making assembly 200 may generally provide a self-contained assembly for producing and/or storing ice. In turn, modular ice making assembly 200 may be selectively mounted within one of the chilled chambers 122, 124, 126 (FIG. 2) or removed from cabinet 102 and used independently (e.g., on a counter top or table spaced away from and outside of cabinet 102).

Modular ice making assembly 200 includes a housing 202 that encloses an icemaker 204. An ice storage cavity 206 may be defined within housing 202 to receive ice as it is produced in icemaker 204. As shown in FIG. 2, one of the freezer compartments (e.g., first top freezer compartment 162) may be formed to complement and receive the housing 202 of modular ice making assembly 200. In turn, modular ice making assembly 200 may occupy substantially all of the corresponding freezer compartment volume. Thus, the ice making assembly 200 may be easily and securely mounted for use within, for instance, first top freezer compartment 162. During instances where additional storage within refrigerator appliance 100 would be desirable, ice making assembly 200 may be advantageously removed from cabinet 102, coupled to a discrete electrical power source, and operated independently of the rest of refrigerator appliance 100.

Turning specifically to FIGS. 3 through 6, exemplary embodiments of modular ice making assembly 200 are illustrated separately from the rest of refrigerator appliance 100. As shown, housing 202 defines a mutually-perpendicular vertical direction V′, lateral direction L′, and transverse direction T′. When modular ice making assembly 200 is mounted within cabinet 102 (FIG. 2), it is understood that each of the vertical direction V′, lateral direction L′, and transverse direction T′ are parallel to the vertical direction V, lateral direction L, and transverse direction T, respectively.

In some embodiments, a water reservoir 208 enclosed by housing 202 is in fluid communication with icemaker 204. Water may be supplied to reservoir 208 (e.g., from an attached water source or, alternatively, manually by a user) and directed to icemaker 204 (e.g., by a separate pump—not pictured). Optionally, water reservoir 208 may be in fluid communication with ice storage cavity 206 to receive water melted from stored ice. Within icemaker 204, water may be frozen (e.g., as nugget or cube ice) before being directed to ice storage cavity 206. For instance, a chute 210 extending between icemaker 204 and ice storage cavity 206 may guide ice as it is motivated (e.g., by gravity) from icemaker 204.

In certain embodiments, a dispenser actuator 212 is mounted to housing 202. For instance, dispenser actuator 212 may be movably (e.g., slidably) mounted below ice storage cavity 206 at a forward portion of housing 202. Moreover, housing 202 may define a dispensing passage 213 between ice storage cavity 206 and dispenser actuator 212. In turn, dispenser actuator 212 may move (e.g., slide along the transverse direction T′) to selectively expose ice storage cavity 206 through dispensing passage 213 (e.g., while dispenser actuator 212 is in a dispensing position, as illustrated in FIG. 5). Ice within ice storage cavity 206 may travel through dispensing passage 213 and out of ice making assembly 200. Thus, dispenser actuator 212 may selectively permit the dispensing of ice from the ice storage cavity 206.

In further embodiments, a cavity door 214 is mounted to housing 202. For instance, cavity door 214 may be movably (e.g., pivotably) mounted in front of ice storage cavity 206 at a forward portion of housing 202. When assembled, cavity door 214 may selectively move between a covered position (FIG. 3) restricting access to the ice storage cavity 206 and an uncovered position (FIG. 6) permitting access to the ice storage cavity 206.

Optionally, an electrical plug 216 or socket may further be mounted to the housing 202, as illustrated. The plug 216 may be electrically coupled with icemaker 204 to supply power thereto. A corresponding mated socket (not pictured) may be provided within cabinet 102 (e.g., within a rear portion 114 of first top freezer compartment 162) and electrically coupled to a power source. Accordingly, when the plug 216 is connected or electrically coupled with the socket within cabinet 102, power may be supplied from the power source to icemaker 204, thereby facilitating ice making operations. Similarly, plug 216 may be electrically coupled to another power source and socket (not pictured) provided outside of cabinet 102 for independent use apart from the rest of refrigerator appliance 100.
